Ex-Melbourne mayor faces more complaints

Complaints about the behaviour of former teacher and ex-Melbourne mayor Robert Doyle by two former students are not being investigated by Victoria Police.

Geelong College referred the students' statements to a specialist police taskforce in December 2015, however, it did not go ahead with an investigation.

"This matter was not investigated by SANO Taskforce," Victoria Police said in a statement on Friday.

Mr Doyle taught at the prestigious college for several years in the late 1970s and early 1980s.

School Principal Peter Miller said the complaints were made to a facilitator contracted by the school to handle such reports.

"There were two callers to the external facilitator and the things that they raised were referred to police," Dr Miller told AAP on Thursday.

"It's very important we do endeavour to support them."

The callers raised issues around their personal experiences of alleged "questionable behaviour".

Mr Doyle's lawyer, Nick Ruskin, said the fresh allegations came as a surprise.

"We are completely unaware of this matter and have received no information about it," Mr Ruskin said in a statement to AAP.

SANO was set up to investigate allegations coming out of a Victorian parliamentary inquiry into child sexual abuse involving religious and non-government organisation and, later, the Royal Commission into Institutional Responses to Child Sexual Abuse.

Mr Doyle quit as Melbourne's Lord Mayor and as chairman of Melbourne Health on Sunday after being hospitalised for stress.

He had previously been accused of sexual harassment and indecent assault.

Former City of Melbourne councillor Tessa Sullivan in December accused the then lord mayor of sexual misconduct against her and colleague Cathy Oke.

A third woman later accused Mr Doyle of touching her leg and making offensive remarks to her at a Melbourne Health awards ceremony in 2016.
